I've been a user of Blender for a very long time (not that I'm skilled though XD ) and while I normally use Cycles or LuxRender, I gave Renderman a try.
I was able to install it successfully, even installing the Maya Renderman even though I don't have Maya, just to get 'it'. But there's a problem.
I modeled a really simple scene:
And while rendering it using Blender's internal framebuffer works,
rendering it with 'it' fails for some reason, and just shows 'it', doing nothing, "Empty" written in its title bar.
Nothing happens no matter how long I wait, Blender becomes non-functional from here on because cancelling the render just takes forever, and I have to force close Blender from the task manager and restart Blender just to take another try.
My Blender version is 2.78a, my Renderman is 21.2, and since I can somehow render images, just not with 'it', I'm sure I installed Renderman and the Blender plugin correctly, but what could be wrong?
Thank you in advance for your support.
